Published on 05 August 2025
Narrabri Shire Council continues to conduct monthly PFAS testing on the Narrabri Town Water Supply.
The latest testing results of the Namoi Reservoir have identified PFAS levels as below the current Australian Drinking Water Guidelines.
This means that the Narrabri Town Water Supply continues to be safe for consumption.

Council will continue to test the water supply monthly and report back to residents.
Mitigation measures remain in place after testing in early July showed the Namoi Reservoir slightly above the current guidelines (PFOS level of 9 ng/L - just above the new Australian Drinking Water Guidelines of 8 ng/L). In line with recommendations from NSW Health, Council conducted an investigation into this slight elevation of results, switching off the Tibberena and Killarney bores.
NSW Health continues to recommend that private bore owners consider testing their groundwater.
